Brand Keys specializes in customer loyalty; providing brand-equity measures that accurately predict future consumer behavior. These measures enable companies to anticipate every shift in a rapidly changing marketplace and to better engage customers. The Brand Keys model is a fusion of the emotional and rational aspects of the consumer's decision making process. This is a critical distinction, as most research methodologies have been "retro-fitted" to accommodate the increasing role of emotion in how consumers approach brands. The Brand Keys methodology was built from the ground up with emotion as a core aspect of evaluation.
